` This inventionrelates to water gages and its object is to provide a substantial device not liable to breakageand damage as is so frequently the case in this class of articles, and consists of several cylinders of glass, the inner one forming a part of a Water tube, the same being surrounded by an outer glass cylinder which is inclosed by a metal casing having longitudinal slots to exhibit the height of water in the gage.

rlhese and other objects and details of the invention are more fully described in the following specification, set forth in theV claims and illustrated in j the drawings, wherein;-

Figure 1 is a side elevation of the improved watei: gage. Fig. 2 is a vertical sectional view. Fig. 3 is a top plan view. Fig. 4l is a cross sectional view. Fig. 5 is a detail view of the gasket to be used in the gage.

The gage consists of a continuous tube for the passage of water embracing the interior glass tube 1() of ordinary thickness and inclosed within an outer tube or cylinder' 1 1 of greater thickness and forming a substantial p rotector for the interior tube but of sufficient transparency for-the observation of -the height of water within the tube 10.

Both of the-tubes are inclosed within a casing 12, whose upper ends are provided with a hexagonal head 13 and threaded at both ends to receive the heads 111 and 15 which make Aconnection with the boiler above and below the water line. The heads 14 and 15 are screwed into the ends of the casing 12 and each of these beads has a recess 16 for the reception of the ends of the tube 10.

interposed-between the heads 14: and 15 and the cylinder 11, are washersor gaskets 17, which, when pressure is exerted ing, said disk upon them b expandand l1 the joints between the heads and the tube 10 so as to make the latter thoroughly water-tight and prevent the escape of either water or steam. This gas-v ket is made with outer flanges 18 and interior flanges 19, the flanges being adapted to lit in the openings which may exist between the adjacent parts. The casing 12 is provided on its several sides, with slots 20 so that the tube 10 and its contents may be observed. I

This device forms a stron and substantial water gage, capable of resisting the rough usage which such devices are generally subjected to and where the metal casing is not sufficient to withstand the accidental blows, the cylinder 11 willafford abundant protection for the interior tube.

It is obvious that the parts may be otherwise arranged or modified without departing from the essential features above described.

The tube 10 is not only protected against injury from violence but it is relieved of sudden changes in temperature by the protecting cyinder which retains its heat and preventsits sudden cooling by rain or snow, or by cold weatherand wind. If the inner tube should break its work would be performed by the outer cylinder and the leakage o-f water and steam prevented until the repairs are made, the outer cylinder thus performing the part of a gage in the usual way. Y

What we claim as new is A gasket adapted to be used in water gages comprising a disk having a peripheral flange at one side only and a central openhaving flanges surrounding said opening and located respectively on the oppositesides, the lastmentioned fianges being of the same diameter and being beveled at their outer edges.

In testimony whereof we affix our signatures in presence of two witnesses.
